Abstract

The use of shafts with reduced diameters in the profiling heads leads to flexion and detuning. Furthermore, the runout of the shafts can cause ejection of the shafts. In order to overcome these problems, the invention proposes to integrate the tuning of the shafts and shaping means through anti-flexion means. A profiling head (1) of a profiling machine comprises at least one shaping cassette (2) containing a set of two parallel shafts (20, 30) on which rollers (201 to 217; 301 to 310) separated by struts (200; 300) are mounted in order to for a rolling tool, and a frame having vertical posts (41, 51) supporting the shafts (20, 30) and a base (60), the posts being provided with vertical adjustment means (44 to 46; 54 to 56). According to the invention, the head also comprises tool alignment (61, 71) adjustment means, mounted laterally on each shaft (20, 30) linked (4, 5) with at least one vertical post (51), and anti-flexion adjustment members (90, 91) mounted substantially in a central position of each shaft (20, 30) linked (4, 5) with the base (60) and an adjustment beam (80) mounted on the vertical posts (41, 51) of the frame parallel to the shafts (20, 30). <0}

Description

TÊTE DE PROFILAGE ANTIFLEXION ANTIFLEXION PROFILING HEAD
ET MACHINE À PROFILER ÉQUIPÉE DE TELLES TÊTESAND PROFILER MACHINE EQUIPPED WITH SUCH HEADS
L'invention se rapporte à une tête de profilage équipée de moyens anti-flexion pour former, par roulage, des plaques de tôle ou équivalent présentant un certain profil, par exemple en U, en V ou autre. L'invention concerne également les machines équipées de telles têtes de profilage.The invention relates to a profiling head equipped with anti-bending means for forming, by rolling, plates of sheet metal or equivalent having a certain profile, for example U, V or other. The invention also relates to machines equipped with such profiling heads.
Dans une ligne de profilage d'une machine à profiler, la tôle est progressivement formée par passage à travers des têtes de profilage équipées de cassettes de roulage. Les machines de profilage comportent une ou plusieurs lignes de profilage jusqu'à atteindre le profil souhaité. Pour chaque ligne, la tôle est déroulée à partir d'une bobine, formée par passage à travers les cassettes de roulage des têtes de profilage, puis recueillie sur un convoyeur de sortie équipé de cisaille de découpe en plaques et enfin empilée. En sortie, des cintreuses peuvent être prévues pour cintrer les plaques de tôle profilées. Des équipements électroniques de pilotage des lignes de profilage sont également prévus.In a profiling line of a profiling machine, the sheet is progressively formed by passing through profiling heads equipped with rolling cassettes. The profiling machines comprise one or more profiling lines until the desired profile is reached. For each line, the sheet is unrolled from a reel, formed by passing through the rolls of rolling profiling heads, then collected on an output conveyor equipped with plate cutting shears and finally stacked. At the outlet, bending machines can be provided for bending the shaped sheet metal plates. Electronic equipment for controlling the profiling lines is also provided.
Chaque cassette de roulage des têtes de profilage comporte un jeu de deux arbres parallèles sur lesquels des galets et entretoises sont montés. La tôle est formée par passage entre ces moyens de roulage présentant respectivement un profil complémentaire, les deux arbres étant réglés en distance sur des montants verticaux en fonction des épaisseurs de tôle. Un châssis de support des arbres comportant les montants verticaux et une embase est prévu. Afin de réduire les coûts et le poids des têtes de profilage, la tendance actuelle est de diminuer sensiblement le diamètre des arbres de montage et des galets. Cependant, l'utilisation de tels arbres entraînent des problèmes de flexion et de déréglage des arbres du fait de leur déformation suite aux contraintes dynamiques générées par le poids des tôles et par leur avancée dans les lignes de profilage. Le réglage ne peut alors être réalisé que par serrage des bagues de roulement des galets, ce qui provoque dans le temps un effet de creusement des bagues par le travail de l'arbre. De plus, les arbres ne sont jamais parfaitement cylindriques et leur faux-rond peut, en rotation, provoquer leur éjection.Each rolling cassette of the profiling heads comprises a set of two parallel shafts on which rollers and spacers are mounted. The sheet is formed by passing between these rolling means respectively having a complementary profile, the two shafts being adjusted in distance on vertical uprights according to the sheet thicknesses. A support frame for the shafts comprising the vertical uprights and a base is provided. In order to reduce the costs and the weight of the profiling heads, the current trend is to substantially reduce the diameter of the mounting shafts and rollers. However, the use of such shafts cause problems of bending and adjustment of the trees due to their deformation due to the dynamic stresses generated by the weight of the sheets and their advancement in the profiling lines. Adjustment can then be achieved by clamping the rollers of the rollers, which causes in time a digging effect of the rings by the work of the shaft. In addition, the trees are never perfectly cylindrical and their runout may, in rotation, cause their ejection.
Pour remédier à ces problèmes, l'invention prévoit de rendre solidaire le réglage de l'ensemble des arbres et des moyens de formage et de prévoir des moyens d'adaptation en flexion.To remedy these problems, the invention provides to make the adjustment of all shafts and forming means integral and to provide bending adaptation means.

Les éléments de réglage latéraux et anti-flexion, montés sur roulements, s'ajustent alors automatiquement aux moyens de réglage vertical. Ainsi, aucun réajustement des moyens de réglage latéraux ou anti-flexion n'est nécessaire, cet ajustement étant asservi : aucun déréglage ne peut se produire, les moyens de transmission du réglage vertical, - poutre et/ou embase -, restant en pression. La poutre peut également servir de contre-flexion.

La tige est introduite dans l'orifice 7a non fileté d'un embout 7. L'autre tige 5 est montée fixe sur la poutre de réglage 80 à l'aide de moyens connus de l'homme du métier. Les éléments de réglage latéraux 61 , 71 et anti-flexion 90, 91 sont montés sur des roulements 3 et 3a, et s'ajustent automatiquement au réglage vertical effectué sur les butées 44 et 54.The lateral adjusting elements 71 fixed to the upright 51 comprise tooling alignment means by centering, as detailed below, while the adjustment elements 61 mounted on the other upright 41 do not include a centering system. . In the exemplary embodiment, an adjusting beam 80 is mounted on the vertical uprights, using connectors 81 and adjusting nuts 82, parallel to the mounting shafts 20 and 30. Anti-bending adjustment elements 90 and 91 are mounted substantially in the central position of each shaft, respectively in connection with the base 60 and the adjusting beam 80 via the rods 4 and 5. The rod 4 has an adjustable height through a set 6 nut / lock nut mounted on a threaded end 4a of this rod 4. The rod is inserted into the non-threaded orifice 7a of a nozzle 7. The other rod 5 is fixedly mounted on the adjustment beam 80 to the using means known to those skilled in the art. The lateral adjustment elements 61, 71 and anti-flexion 90, 91 are mounted on bearings 3 and 3a, and automatically adjust to the vertical adjustment made on the stops 44 and 54.
De manière plus détaillée, s'agissant du réglage d'alignement latéral, les figures 2a, 2b et 2c illustrent une vue latérale et des vues en coupe de la figure 1 concentrée sur un élément 71 de réglage d'alignement de l'outillage. Un tel élément comporte deux boulons de centrage à vis filetées 72 et 73. Les boulons sont montés sur deux flasques 74 et 75, disposés extérieurement à deux parois 57 et 58 du montant 51 , pour traverser les parois 57 et 58.In more detail, with regard to the lateral alignment adjustment, FIGS. 2a, 2b and 2c illustrate a side view and sectional views of FIG. 1 concentrated on an alignment alignment element 71 of the tooling. Such an element comprises two centering bolts with threaded screws 72 and 73. The bolts are mounted on two flanges 74 and 75, disposed externally on two walls 57 and 58 of the upright 51, to pass through the walls 57 and 58.
Dans le cadre du réglage latéral d'alignement de l'outillage, un élément de réglage anti-flexion est illustré en figure 3a. Un tel élément 90 comporte une bague conique 92a fendue longitudinalement selon l'axe X1X de l'arbre 20. La bague présente une épaisseur suffisante pour servir d'entretoise. Sur cette bague 92a, est monté un roulement 3a dont le palier interne 30 présente la même conicité que celle de la bague 92a. La position relative du roulement 3a sur la bague est réglée latéralement par déplacement relatif (flèche F) de ce roulement le long de la bague conique 92a à l'aide d'un écrou 32 en liaison avec une portion filetée 93 de la bague fendue. Un tel déplacement induit simultanément un resserrement ou desserrement asservi de cette bague.As part of the lateral adjustment of tool alignment, an anti-bending adjustment element is illustrated in FIG. 3a. Such an element 90 comprises a conical ring 92a slotted longitudinally along the axis X 1 X of the shaft 20. The ring has a thickness sufficient to serve as a spacer. On this ring 92a is mounted a bearing 3a whose inner bearing 30 has the same taper as that of the ring 92a. The relative position of the bearing 3a on the ring is set laterally by relative movement (arrow F) of this bearing along the conical ring 92a by means of a nut 32 in connection with a threaded portion 93 of the split ring. Such a displacement simultaneously induces a constriction or loosening of this ring.
Un autre élément anti-flexion 91 est illustré en figure 3b. Cet élément se compose d'une bague fendue 92b de même type que la bague 92a et d'un roulement 3a à palier interne conique 30, identique au roulement associé à la bague 92a. Un déplacement latéral entraîne le glissement du roulement 3a sur la bague 92b dont le diamètre reste constant par augmentation ou diminution de l'ouverture de la fente de la bague. Le déplacement est assuré par le galet 305 qui appuie contre le roulement 3a.Another anti-flexion element 91 is illustrated in FIG. 3b. This element consists of a split ring 92b of the same type as the ring 92a and a bearing 3a conical inner bearing 30, identical to the bearing associated with the ring 92a. A lateral displacement causes the rolling of the bearing 3a on the ring 92b whose diameter remains constant by increasing or decreasing the opening of the slot of the ring. The displacement is provided by the roller 305 which bears against the bearing 3a.
La figure 4 illustre en coupe transversale selon un plan variable A-A de la figure 1 , les deux éléments de réglage anti-flexion 90 et 91 des figures 3a et 3b. La figure met en évidence l'utilisation de paliers externes partiels 94a, 94b formés d'une section de cylindre disposée au regard de la tige 4 de liaison à l'embase 60 ou la tige 5 de liaison à la poutre 80. Les extrémités des tiges 4 et 5 viennent se fixer respectivement dans les paliers partiels 94a et 94b. Cette réduction de longueur de palier, avantageuse en terme de coût, est justifiée par le fait que seule une portion de palier externe est utile pour le réglage. Les paliers internes 30 restent complets.FIG. 4 illustrates, in cross-section along a variable plane AA of FIG. 1, the two anti-bending adjustment elements 90 and 91 of FIGS. 3a and 3b. The figure highlights the use of external bearings partial 94a, 94b formed of a cylinder section disposed opposite the connecting rod 4 to the base 60 or the rod 5 connecting to the beam 80. The ends of the rods 4 and 5 are respectively fixed in the bearings Partials 94a and 94b. This reduction in bearing length, advantageous in terms of cost, is justified by the fact that only an outer bearing portion is useful for adjustment. The inner bearings 30 remain complete.
